Recommendations

For reliable operation, use the replacement battery with the original HP AC adapter and charging circuitry. Calibrate the battery periodically by charging to full and then discharging to a low level under normal use to help the operating system estimate remaining capacity accurately. Store unused batteries in a cool, dry place at partial charge (approximately 40–60%) and avoid prolonged storage at full charge or in hot environments.
